论文摘要
微孔子中的光学参数振荡（OPO）有望成为一种有效且可扩展的片上相干可见光生成的方法。但是，到目前为止，仅报告了<420 THz（可见带的边缘）处的红光。在这项工作中，我们演示了芯片OPO覆盖> 130 THz的可见光谱，包括红色，橙色，黄色和绿色波长。特别是，使用泵激光器在近红外在386 THz到391 THz中进行扫描5 THz，该信号从395 THz的近红外调谐到528 THz的可见光，而惰轮则从近红外调谐到254 Thz的378 THZ，在378 Thz的近红外。我们证明了274 THz的最宽的信号式分离比八度跨度更重要，并且是迄今为止纳米光OPO所证明的最宽的。我们的工作清楚地证明了非线性纳米光子学如何将光从易于访问的紧凑型近红外激光转变为靶向可见波长感兴趣的光，这对于光谱和计量系统的现场级部署至关重要。
Optical parametric oscillation (OPO) in a microresonator is promising as an efficient and scalable approach to on-chip coherent visible light generation. However, so far only red light at < 420 THz (near the edge of the visible band) has been reported. In this work, we demonstrate on-chip OPO covering > 130 THz of the visible spectrum, including red, orange, yellow, and green wavelengths. In particular, using a pump laser that is scanned 5 THz in the near-infrared from 386 THz to 391 THz, the signal is tuned from the near-infrared at 395 THz to the visible at 528 THz, while the idler is tuned from the near-infrared at 378 THz to the infrared at 254 THz. The widest signal-idler separation we demonstrate of 274 THz corresponds to more than an octave span and is the widest demonstrated for a nanophotonic OPO to date. Our work is a clear demonstration of how nonlinear nanophotonics can transform light from readily accessible compact near-infrared lasers to targeted visible wavelengths of interest, which is crucial for field-level deployment of spectroscopy and metrology systems.
